KC724 Board Features and Operation
User LEDs (Active High)
Callout
DS13 through DS20 are eight active-High LEDs that are connected to user I/O pins on the
FPGA as shown in
These LEDs can be used to indicate status or any other
purpose determined by the user.
User DIP Switches (Active High)
Callout
The DIP switch SW2 provides a set of eight active-High switches that are connected to user
I/O pins on the FPGA as shown in
. These pins can be used to set control pins or
any other purpose. Six of the eight I/Os also map to 2 x 6 test header J125 providing
external access for these pins (callout
